If you want to discourage others from making edits to your Microsoft PowerPoint presentation or let them know the file you sent is the final version, you can do so by making it read-only. Here's how it's done.

Note: While making your PowerPoint presentation read-only is a good deterrent from having others edit your content, it's easy to unlock a read-only presentation. It's by no means un-editable.

Open the presentation that you want to make read-only, then click the "File" tab.

Next, in the left-hand pane, select "Info."

You'll now see a "Protect Presentation" section, which lets you (to an extent) protect against any editing of your presentation. Click "Protect Presentation."

Once selected, a drop-down menu will appear with these four options:

  • Always Open Read-Only: This asks the reader to opt-in to edit the presentation. This prevents accidental edits.
  • Encrypt with Password: This password protects your presentation.
  • Add a Digital Signature: This adds an invisible digital signature to your presentation.
  • Mark as Final: This lets the reader know that this is the final version of the presentation.

All of these options are good for protecting the integrity of your Microsoft PowerPoint, but the two we'll need here to make the presentation read-only are (1) Always Open Read-Only and (2) Mark as Final.

Selecting either option will prevent the reader from editing the presentation–unless they opt-in to do so.

If you chose the Always Open Read-Only option, the reader will see this message when opening the presentation:

"To prevent accidental changes, the author has set this file to open as read-only."

If you chose the Mark as Final option, the reader will see this message:

"An author has marked this presentation as final to discourage editing."

In either case, your Microsoft PowerPoint presentation is now set to read-only. However, in both cases, all the reader has to do to edit the presentation is click the "Edit Anyway" button.

How to Display Steam’s Built-in FPS Counter in PC Games

Steam has a built-in feature that will display your frames per second (FPS) while playing PC games. It's quick to enable and works in nearly any Steam game. Here's how to see your FPS in Steam games on Windows 10, Mac, or Linux.

First, click Steam > Settings in Steam.

Click Steam > Settings.

In the Settings window that appears, click "In-Game" in the left sidebar.

Click the "In-game FPS counter" box and select your preferred location. By default, it's set to "Off" and won't be displayed. You can choose Top-left, Top-right, Bottom-right, or Bottom-left to place the counter at any corner of your screen.

By default, the FPS counter will be gray, which will make it blend in with many games. To make it easier to read, check "High contrast color," and the FPS counter will have its numbers displayed in a bright neon green that stands out better.

Select "In-Game" and choose an option from the "In game FPS counter" box.

When you're done, click "OK" to save your settings and launch a Steam game.

Note: If you Alt+Tab out of a game in progress and change these settings, you'll have to close and reopen the game before they take effect.

Here's how the standard FPS counter looks at the top-left corner of a game:

In high-contrast mode, the brighter FPS counter looks like this:

It's up to you whether you want a more noticeable and visible FPS counter or one that blends better into the background until you look for it.


This isn't the most powerful FPS counter compared to other tools, but it's simple and built-in. For more control, check out other in-game FPS-monitoring tools.

Can You Tell When Your Apple Watch Has a GPS Lock?

Most GPS running and multi-sport watches tell you when they have a lock to the GPS satellites overhead. Unfortunately, the Apple Watch doesn't—at least not without using a third-party app like Runkeeper or Intervals Pro. But there are a couple of workarounds.

Most of the time, the GPS in your Apple Watch should work invisibly. Within a minute or two of starting an outdoor workout or other GPS-tracked activity, it will just have a good lock. And, if there are any gaps or short sections it loses signal for, it will use your pace history, stride length, the accelerometer, and other personalized information to estimate and fill things in.

bad GPS
This seems like an unlikely running route.

However, while you can't confirm your watch has a GPS lock mid-workout, you can check it's using "Location Services." These are, basically, GPS plus Assisted GPS (aGPS), cellular positioning, Wi-Fi network positioning, and any other way your watch can possibly find out where you are.

To check, swipe up on the main watch face to access the Control Center. If your watch is using Location Services, there will be a solid purple arrow in the top right corner. (If the purple arrow is just a hollow outline, it means that an app could possibly receive location data but isn't currently doing so.)

Now, this just tells you that your watch is using Location Services. It doesn't mean that it's getting accurate location data (or any at all). Assuming all is well with your watch, it'll get a GPS signal as soon as it can. If you're indoors, under trees, or if there's something else interfering with it, it might not have GPS at the current moment.

If you're not sure your GPS is working and need to troubleshoot it—or just want to guarantee you've got a lock before an important timed event—there's a way to force things: use the Maps app.

On your watch, open the Maps app. To find your location, it has to use Location Services (you can check in the Control Center, if you like.) Most importantly, it will display the results right in front of you.

On the left, the GPS hasn't got a good signal yet. On the right, it's accurate to a couple of meters.

The size of the location circle will give you an idea of how good a GPS signal you have (or if you have one at all). GPS is accurate to a couple of meters, so if the circle is larger than that, your watch hasn't got a strong satellite fix yet. If you're standing out in open terrain and still can't get a lock, something's probably up with your GPS and you should contact Apple support. (Or, I suppose, nuclear war is about to break out; in which case, there's no need to contact Apple.)

Tip: Your watch also piggybacks off your iPhone's GPS signal. If you're trying to troubleshoot your Apple Watch's GPS signal, turn off your phone and then open Maps on your Watch.

How to Watch YouTube Picture-in-Picture in Safari on Mac

Posted: 16 Jan 2021 10:57 AM PST

The dedicated Picture-in-Picture (PiP) button makes it quite easy to play videos in a floating, movable window on the Mac. Unsurprisingly, the YouTube player doesn't support this feature. Thankfully, there's a hidden way to watch YouTube Picture-in-Picture in Safari on Mac.

Many websites in Safari (and the TV app) come with the Picture-in-Picture button. You simply press it to enter the floating media player.

Tap the PiP button in supported video players

The process for YouTube videos is different. First, open the YouTube website in Safari and navigate to the video that you want to watch in Picture-in-Picture mode.

Next, right-click once in the video window. You'll see YouTube's own context menu.

Right-click once more with YouTube's menu still on-screen to open Safari's context menu. Here, choose the "Enter Picture in Picture" option.

Instantly, the video will start playing in a floating media player.

You can drag the edges of the player to resize the window and click and drag to move it around. You can dock it to either one of the edges of your Mac's screen.

Press the Play/Pause button to play or pause the video. Click the "X" button to exit and stop playback, or select the Picture-in-Picture button to go back to the YouTube player in Safari.


The Picture-in-Picture feature for YouTube isn't just limited to the Mac. You can use it on your iPad and even on your iPhone!

How to Change the Shortcut That Opens Windows 10’s Game Bar

Usually, Windows+G opens up the Xbox Game Bar in Windows 10. But if you'd like to launch the Game Bar with a custom keyboard shortcut, Windows Settings has you covered. Here's how to set it up.

First, we'll need to visit Windows Settings. Open the Start menu and select the "gear" icon on the left side of the menu, or you can press Windows+i on your keyboard.

In the Windows 10 Start Menu, click the "gear" icon to open Settings.

In Settings, select "Gaming."

In Windows Settings, click "Gaming."

In "Xbox Game Bar" settings, scroll down until you see the "Keyboard shortcuts" section.

The first entry in the list is "Open Xbox Game Bar." To set your own custom shortcut, click the box beside "Your shortcut," then press the keyboard combination you'd like to use. For example, we entered Control+Shift+G.

Click the Xbox Game Bar shortcut box and enter a keyboard shortcut.

If you try a combination that's already taken by something else, you'll see an error message. If that's the case, try a different shortcut.

After that, scroll down to the bottom of the "Keyboard shortcuts" list and click the "Save" button. You must click Save for the new keyboard shortcut to take effect.

Tip: You can change keyboard shortcuts for other Game Bar functions like screen recording and live broadcasts here, too.

In Windows Settings, click "Save."

Press your new shortcut anywhere in Windows 10 and the Xbox Game Bar will appear.

If you want to disable your custom Game Bar shortcut in the future, revisit Windows Settings > Gaming, then clear the "Open Xbox Game Bar" shortcut text box and click "Save." You can also click the "Reset" button at the bottom of the list to clear all custom shortcuts. Happy gaming!
